In one week, 1,000 companies have signed up for Amazon's Oracle-killer service

A week ago, Amazon Web Services chief Andy Jassy stood onstage at
the company's annual tech conference and
promised "freedom" to frustrated Oracle users. Now Amazon
says that over 1,000 customers have already taken him up on the
offer.

The "freedom" came in the form of a new tool called AWS
Database Migration Service that helps these users jump ship from
the Oracle database to Amazon's competitor, Amazon Aurora,
or to some of the other Oracle competitors that Amazon hosts on
its cloud-computing service.

Oracle has a really strong hold on its database customers. They
love the product and they use it to run their most important
applications. But, as
we've previously reported, many do not like how
Oracle sells and charges for it for the database and the hardball
tactics it has been known to use with its customers.

But there wasn't a lot of choice in the matter. The other
traditional large-scale database providers, like Microsoft, all
had their own licensing issues.

One thousand customers, even in a week, is a drop in the
bucket compared to Oracle's enormous global cadre of customers.
But if this tool keeps going gangbusters, the battle
between Amazon and Oracle will be an interesting one to
watch.

Meanwhile, Amazon says that its customers love its new Aurora
database, making it the "fastest-growing service in the history
of AWS," though it didn't offer specific numbers to explain
those claims.
